I bought this new for around 18,000 yen. I'm selling it because I don't read it. It seems I threw away the original special case. There are no extras, and the 20 books in the photos are all that's included. There's no sun damage, and it's in good condition because I haven't read it much. I don't think there are any markings, but I apologize if I missed anything. While inspecting, I noticed a fold/tear on the cover in the eighth photo, but it's a small area. Based on the above, I think it's a used, beautiful item (subjective). However, please refrain from purchasing if you are sensitive to such things.
